I have been meaning to buy a Didymos for ages (at least 4 years!) but for some reason never got around to it. Then last week I slipped a disk, and while discussing carrying children with my chiropracter he suggested I went back to a front carry for a while until my back is stronger. The only front carry slings I had were cotton jersey - lovely with a newborn, but a bit stretchy for a 9 month old fidgit bum, so I bit the bullet and ordered a size 5 Lena (I'm a size 8/10 and 5'3" - so it will be plenty big enough for me), this arrived very speedily from Free Range Kids.
I am thrilled with it. The fabric is a beautiful quality and lovely colour, and while I am not yet up to carrying a 20lb baby, I have practiced some of the different carries with my daughter's doll! It may look daunting from the instructions, but having used tie on wraps before it soon became clear - I have yet to look at the DVD that came with it, but I am sure that watching that will clear up any lingering doubts.
